Máté Eckl 1bfc2bc7ad netfilter: doc: Add nf_tables part in tproxy.txt
Recently, transparent proxy support has been added to nf_tables so that
this document should be updated with the new information.

- Nft commands are added as alternatives to iptables ones.
- The link for a patched iptables is removed as it is already part of
  the mainline iptables implementation (and the link is dead).
- tcprdr is added as an example implementation of a transparent proxy

Florian Westphal fd158d79d3 netfilter: tproxy: remove nf_tproxy_core, keep tw sk assigned to skb
The module was "permanent", due to the special tproxy skb->destructor.
Nowadays we have tcp early demux and its sock_edemux destructor in
networking core which can be used instead.

Thanks to early demux changes the input path now also handles
"skb->sk is tw socket" correctly, so this no longer needs the special
handling introduced with commit d503b30bd6
(netfilter: tproxy: do not assign timewait sockets to skb->sk).

Thus:
- move assign_sock function to where its needed
- don't prevent timewait sockets from being assigned to the skb
- remove nf_tproxy_core.
